The year’s usual slow period, January and February, brought a handful of significant restaurant openings in the Bay Area — Kin Khao, Pizzahacker, Victory Hall et al. — plus new cafes from established coffee favorites like Blue Bottle and Sightglass. But in March, the winter melted and the floodgates opened for a deluge of restaurant openings.

For your checklist dining purposes, we have taken the liberty of listing out a few of the more notable ones to open last month alone, starting in San Francisco and then extending beyond the city limits; time will tell if they’ll be among the year’s best openings, but for now, we’re classifying them as notable. More information is available in prior coverage, when applicable, and do note that hours may change:

The Square, North Beach: The two chefs behind Sons & Daughters took over the old Bottle Cap/Washington Square Bar & Grill to open a new restaurant named the Square; will they be able to break the streak of bad luck that plagued the address in the last decade? The menu has evolved into a communal eating affair, though the cheeseburger remains a constant. 1707 Powell St., near Union, San Francisco; (415) 525-3579 or thesquaresf.com. Dinner Wednesday-Sunday. [Prior coverage]

Humphry Slocombe, Embarcadero: The popular Mission District ice cream shop opened its first spinoff within the Ferry Building, in the slot that used to house Ciao Bella, right across the way from Blue Bottle. 1 Ferry Building, San Francisco. (415) 550-6971 or humphryslocombe.com. Open daily. [Prior coverage]

Trou Normand, SoMa: Trou Normand is the Bar Agricole sequel, set in the gorgeous and newly restored 140 New Montgomery building downtown. As with its big sister, cocktails are the specialty, with local produce and a stunning design. 140 New Montgomery St., near Howard, San Francisco; (415) 975-0876 or trounormandsf.com. Open 5-11 p.m. weekdays; hours to expand in coming weeks. [Prior coverage]

Terra Cotta Warrior, Sunset: While bigger budget places grabbed more headlines, the sleeper hit of the month might be third Xi’an cuisine restaurant to open in San Francisco in the last 12 months. Tasting Table’s Jonathan Kauffman called it the most beautiful and the tastiest of the three. And the Weekly praised it as “some of the most ethereal hand-rolled noodles known to humanity.” 2555 Judah St, between 30th and 31st, San Francisco. (415) 681-3288

Squat & Gobble, West Portal: It’s been a long road back for the West Portal cafe, which was destroyed in a fire. Millions of dollars later, it’s back open with a whole new look and kitchen. Squat & Gobble: 1 West Portal, at Ulloa, San Francisco. (415) 665-9900 or squatandgobble.com. Open daily. [Prior coverage]

San Tung #2, Sunset: Wings. From San Tung. Next door. That is all. 1031 Irving St., between 11th and 12th, San Francisco. (415) 242-0828. Open for lunch and dinner, Thursday-Tuesday. santungrestaurant.com

Chocolatier Blue, Mission: The tony Berkeley chocolate shop expanded to San Francisco last year with a Financial District branch, and now it’s opened another place in the city: right in the Mission. 905 Valencia Street, near 20th, in San Francisco. (415) 648-1010 or chocolatierblue.com. Open daily.

Barrel Head Brewhouse, Western Addition: Beer is the name of the game at this sprawling two-story brewpub. They’ll make their own eventually, but for now they’ve collected 30 or so brews to accompany a gastropub-ish food menu from a Monk’s Kettle vet. 1785 Fulton St. (at Masonic Avenue), San Francisco; (415) 416-6994 or barrelheadsf.com. Lunch and dinner daily. [Prior coverage]

Il Casaro, North Beach: While Steps of Rome Trattoria was reborn as SFFCC (see #11), the cafe is now Il Casaro, a mozzarella bar and Neapolitan pizza parlor; Tablehopper has a menu. 348 Columbus Ave., between Vallejo and Grant, San Francisco. (415) 677-9455 or ilcasarosf.com. Lunch and dinner daily. [Prior coverage]

Andytown, Sunset: The Outer Sunset got itself a new coffee roaster and coffee shop with Andytown’s arrival. The Weekly has a nice write-up and look around the place. 3655 Lawton Street, between 42nd and 43rd, San Francisco. (415) 753-9775 or andytownsf.com

The Cooperage, Lafayette: A team of San Francisco restaurant veterans led by partner Andrew McCormick and chef Erik Hopfinger opened this 300-seat American restaurant and bar in Lafayette’s old Petar’s location. 32 Lafayette Circle, at Mt. Diablo Boulevard, Lafayette, (925) 298-5915 or thecooperagelafayette.com. Open daily. [Prior coverage]
